Verdict
Intel Xeon 6766E
8.6 / 10 Expert Rating
The Intel Xeon 6766E trades per-core performance for AMD-style core density, a strong pick for horizontally-scaled cloud-native fleets.
Intel Xeon 6780E
8.8 / 10 Expert Rating
The Intel Xeon 6780E is the higher-clocked half of the 144-core E-core pair, for cloud-native fleets that want core density without giving up as much per-core speed.
